Great Product! Did not fit on my Lycoming O-290-D2 engine because of the 5 point engine mount (on the firewall) that I have. I highly recommend getting a hold of the infamous Bill at the Lab and having him work through your model to make sure its applicable if its a weird one like mine was. Basic rules are no 5 point engine mounts, 45 degree angled oil cooler line, and a spacer depending on your accessory case setup. Wish it would have fit for the benefit of a pleated filter instead of a screen but oh well.

Part selection criteria online and catalog raises more questions than answers. quick call to Casper Labs cleared it up, supposed to be new numbering system coming soon.

Casper Labs CL1000A-STC Adapter Only

Great adapter. Call Bill at Casper Labs before you order. He is extremely knowledgeable about his products and knows exactly what you need to install it. I have a 65 year old airplane that has seen a lot of changes and Bill knew exactly what to look out for. Aircraft Spruce carries more parts for the Casper Labs Oil Filter Adapter than are listed above. Call Bill (great guy) (561-575-3157) before you order the wrong stuff, hell give you all the part numbers for your specific application.

Very nicely machined part, nice fit and easy to install. You will need an AN823-8 elbow fitting for the oil cooler hose, this is in the instructions. If you position the elbow down and inboard the hose will just clear the magneto and the adaptor and the filter, it is close but they dont touch and dont interfere. Filter change is much easier than with the OEM adaptor.

Works great!

Well made and designed.

Installed on a Piper Colt with a Lycoming O-290-D2. The install was easy and the fit great with the quality of the kit being top notch. A MUST: Call Casper Labs prior to your install. They actually want you to call them because there are so many variations and applications regarding aircraft engines and they will tell you exactly what you need for your specific application. Chances are that you will talk to Bill, who has many years of experience with the extensive knowledge to match. He spent about 30 minutes over two calls with me, told me exactly what I needed for my kit and explained it all in detail. I am extremely pleased and highly recommend this high quality kit. The customer service is fantastic!

Outstanding support answering my questions with details and instructions from Bill.

Excellent adapter! Easy to install. In my Lancair, with very low cowling clearances, I used a K&N HP-1002 filter, Caspers recommendation. Clearance to the oil line is tight. I already had a 90 degree fitting on it, needed to rotate the hose out of the way.

Excellent quality and works as advertised. Installed easily on Citabria 7GCAA w/O-320B@B. I'm always skeptical about how well a product performs vs what they advertise. On the first oil change I punched a back drain hole on the bottom of the filter and let it drain back to the sump. When I removed the filter it didn't spill a drop. That is nice. No mess at all.

Very clean installation! No hose fabrication or holes to be drilled. Just torque it down and you're good to go! Great angle for catching oil during oil changes too.

Probably one of the easiest mods I have performed on an aircraft. Bolted right on to a Lyc O-320 without any issues at all!

I installed PN 08-01236 (with the shorter CH48108-1 filter) on my 1967 7KCAB Citabria with an IO-320E2A. It was a snug fit but no additional parts were required. Some things to consider: - There is minimal clearance between the adapter and the tach cable, about 1/8 at the front of the adapter where it has been milled to accommodate the connector, and about 3/16 between the adapter and tach cable at the rear of the adapter - once the adapter is installed, there was just barely clearance to install the vernatherm (coming up from the bottom) in the adapter, and you might want to fit it in place before you bolt the adapter to the case - we had to rotate a 45 degree fitting for an oil line to get clearance for the filter itself, and - we wrapped that line with sacrificial tape to prevent it rubbing against the filter. (Ideally that line could be about an inch longer to clear the filter without excessive hose flop.) I gave it 4 stars for the ambiguity in the installation.

The first unit i was sent looked 2nd hand, or was previously installed and returned. It also had no installation manual and all the accessories were missing. I emailed Spruce and was simply told by customer service to contact the manufacture... I was very annoyed. After an email to Jim Erwin himself, I was sent a replacement and was able to return the first unit, although UPS were a real pain as well. I ended up having to take the package into UPS for return delivery, as they never came to collect it. Another thing I would like to add is, i did speak to the manufacturer and they were very helpful, and the product is sound. Thats why I gave 4 stars regardless of the ordeal I encountered.

Had one problem with installation in that the aluminum washer supplied for the vernatherm plug tends to be pinched out when tightening. Otherwise, the quality and support are excellent. I had a question about the installation and Casper Labs picked up right away. The owner of this business is very knowledgeable and told me more about my aircraft than I knew myself. Thanks!

There was one piece missing to install it on my engine 0-235 that was not specified it was supposed to fit right on.

Didnt fit as specifications stated. Call Casper Labs prior to ordering to get any additional parts necessary for your particular application.

Would have been a 5 star until we called Casper Labs to order the spacer block to allow it to fit the airframe and were told that this does not work with any metal fuselage Piper aircraft due to the construction of the engine cradle. Other than that it was a nice complete kit with thorough instructions that could have been put on in 30 minutes.
